[TASK] Updated Examples for Usage

Added default and inline usage for the optional attribute "allowedTags"

Maybe you have to think about the name, cause in
http://php.net/manual/de/function.strip-tags.php the second parameter is
called "allowableTags", and not "allowedTags" This can lead to a quick
overlooked error ;)
